You need to look at a lot more info, room type, batcave or ambient light, sound requirements. If you are all apple tv then you only need dolby digital 5.1 apple tv is decent, I have used it in a 158" 2:35 screen and looks fine. Some movies are better than others. The larger screen will show any issues with the encode. But for comedies, animation,etc I am okay with it, it is hard to tell to me. But blu ray is the way to go, star wars, transformers, dark knight etc. Once you get that hd audio and the full blue ray resolution and depth it ishard to go back. It just depends on how picky you are. One thing, if you like the atv quality etc.don't look to hardif you are happy, stickwith happy. This stuff is like crack, once you start it is hard to stop. If you are dark room do not care about 3d a lot go with jvc x35 ,golden ear tritons, carada screen, apple tv. If you get hooked on the hd audio, blu ray definition, I have used most of the streamers, if you do notneed 3d openelec on a intel nuc, is sweet!
If you want 3d and are cool with no or manual movie jukebox go mede8er 1000 or 600. Good luck, a lot of research in your future.
